Explanation

A hybrid search approach combines keyword (lexical) search with semantic (vector-based) search, making it ideal when queries span both structured lookups and natural language questions. Keyword search ensures exact matches for precise terms like model numbers or part IDs. Semantic search understands intent and meaning, enabling accurate results for questions like 'How do I reset my device?' Using keyword search only (A) would fail on natural language queries with no exact match. Using semantic search only (B) would struggle with precise alphanumeric identifiers where exact string matching is more reliable. Hybrid search delivers the best accuracy across both query types.
